RUFUS N. CAMBERLAIN, OF DEPEW, NEW YORK, ASSIGNOR TO GOULD STORAGE BATTERY COMPANY, OF DEPEW, NEW YORK.

STORAGE BATTERY.'

To all whom it may concern.'

Be it known that l, .Horus ll. (li-nuern- LAIN, a citizen of the United States, residing` at Depew, in the county of Erie and State of New York, have invented a new and useful Improvement in Storage Batteries, of which is a sectional elevation of a battery receptacleor tank provided with my improve ments. Fig. 2 is a top plan view thereof with the cover partly removed. Fig. 3 is a fragmentary vertical section through the cover and the upper part of the tank at right angles to Fig. l, in line 3-3, Fig. 2. Fig. el is a fragmentary vertical section through the cover and upper part of the tank lining, in linel 4 4, Fig. 2, on an enlargedscale.

Like letters or' reference refer to like parts in the several figures.

A represents the outer portion of a foursided battery tank or vessel, preferably of wood and provided with supporting rollers a and spacing side pieces a of porcelain or other non-conducting material, two of these tanks A A being preferably secured together' side by side in a well known manner.

B represents the inner portion or lining of the tank which is preferably constructed of antimonial sheet lead and secured in the outer or Wooden portionby a layer of cement in the usual Way. YThis lining is provided above the outerl portion with a. .top flange C comprising an outwardly-extending bottom portion or horizontal shoulder c and an up- Wardly-extending marginal portion c having at its upper end an inwardly overhang ing lip c2. The horizontal shoulder,l c supports the cover D which rests withits marginal portion d on this shoulder. The lip c? extends inwardly only over the outer porA tion of the horizontal shoulder c, leavingthe inner portion of the shoulder exposed, und the cover D does not extend outwardly to the upright portion c. This permits a solid or undivided cover to be placed upon the Specification of Letters Patent.

shoulder 0. The cover is provided inside of its marginal portion or flange (l with an upright shoulder nl, formed preterably' by arranging the marginal portion d of the cover at a lower level than the body portion of the cover, The channel or groove which is formed above the horizontal shoulder 0 or the lining and the horizontal marginal flange (l of the cover, and which is bounded on the outside by the upright portion o of the lining and on the inside by the upright shoulder d of the cover, is iilled with a cement packing E which is applied in a plastic condition and hardene and secures the cover securely in place. rlhe inwardly overhanging lip G2 of the lining prevents this packing from being raised out of its seat by the shocks to which the receptacle may be subjected when used' on vehicles. Any suitable asphalt or petroleum con'iposition or cement may be used for this packing.

The cover, which may be made of any suitable material, for instance, hard rubber or antin'ionial lead, is provided with upright collars or short tubes F, through which the terminals G or' the plates G entend upwardly. rilhese collars or tubes preferably taper upwardly and are considerably larger in diameter than the terminals. The space between these collars or tubes and the ternir nale Ais filled by bushings or packing sleeves H of yielding, non-conducting material which hold the terminals yieldingly in po sition and close the openings so tightly that the electrolyte is not liable to spattcr or leak through the same. These bushings are ref# erably made of sponge rubber which 1s so vulcanized as to have a smooth nish on the inner and outer sides, as-indicated at 7L h, to fit closely against the terminals and collars. These soft and impervious bushings are so y thick as to allow of considerable lateral movement of the terminal in the opening of the cover under the jarring which the battery is liable to receive when used on a railway car or other vehicle, and capacity of yielding in a lateral direction is greater than the possible lateral play-of the plates in the vessel and prevents the jars or shocks Jfrom being transmitted to the cover and the cement packing and injuring or destroying the same.

The cover is provided with the usual vent opening z' closed by a stopper l. 1

The parts by which the jar or tank is close@ et 'the top are not corrodible to any Considerable extent and remain in goed iforliing eonrlition for n long time under the usual conditions of use, thereby mein l taining e, practically acid-tight closure for n longj -nie and preventing leakage or spilling of the acid.,

` l olziiin my invention:

l. The combination of n battery VeSSel h.,vingj a flange comprising a horizontal lionlder extending outwardly from the up per portion of the body of the vessel, on up- 'right portion extending from the outer portion of etnici shoulder upwardly, and e lip extending from the top of tne'nprigiit portion inwardly over the outer port-ion of seid shoulder, leaving the inner gortion of said slionlfler expoeed, n solid cover rooting fmtwie'e with its marginal portion on said. horin zontnl slioniden-e cement peeking arranged between tlie edge of 'theeover and the upright portion and below the lip of seid top y flange, enti 'terminals extending through said Cil cover, substantially set forth.

2. The combination of e. battery Vessel 'having e top linnge'comprisinge horizonoil shoulder extending outwardly from the up-` per portion of the body of the vessel, en up-` rightportion extending from the outer portion of seici Shoulder upwardly, and a lip er@ tending from the 'top of the upright portion inwardly over the enter portion of finiti Shoulder, leaving the inner portion of said .Shoulder exposed. n solid cover resting with its marginal portion on seifi horizontal ebonhler and having en upright shonlfer on ranged inside oiE said marginal portion and forming with said upright portion o the top linnge a channel wbioli is overhnng by said lip., :3 cement packing arranged in said, :linnnel below1 seid lip, and terminals eX- tending through the cover, substantially set forth.

3. The combination of a, battery .Vessel having n top liange comprising a horizontal shoulder extending outwardly from the upper portion of the body of the vessel, an npright portion extending from the outer portion of Said shoulder upwardly, and :L lip extending from the top of said. uprigat portion inwardly, :t cover provided *with a mnropenings in the cover, and bushings of soft y rubber arranged in seid openings around vthe terminals, substantially as set forth. y
